SPECIFICATION forming part of Letters Patent No. 299,227, dated May 27, 1884; Application filed January 14, 1884. (No model.)

To @il whom, it may concern:

Be it known that I, WILLIAM J. Knysna, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Chimney Gaps and Vcntilators; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to improvements in caps and ventilators for chimneys, and will be fully described hereinafter.

In the drawings, Figure l is a vertical sectional view of my improved cap and ventilator. Fig. 2 is a perspective view ofthe same 5 and Fig. 8 is a vertical sectional view ou the line w x ol' Fig. l.

A is the pipe, to the top of which the cap is attached, and which may be secured on top of the chimney B in anysuitable manner. Fastened on, opposite each other, to the pipe A are the sheet-metal cone-frustums G C, to form the ventilator and cap. These cone-frustums C are provided with a flange, a, projecting around their base. rllhey are fixed to the pipe so that the top of this last will be somewhat higher than the upper edge of the cone-frustum top c, and a part -of the flange a, as well as of the base ofthe cone-frustums, is cut out or shaped so that when the two are fastened in place around the pipeA this latter is encircled by the cone-frustums, except at the center, where a space is left open between the same. The mode of fastening is of course immaterial, as, whether bolts, rivets, or simply solder be used, my invention remains the same. The upper half of the space left between the opposite cone-frustums is covered over by a sheetmetal band, D, the ends of which are suitably fastened to the flange a on aline passing horlzontally through the center of said eone-frus tums. From the point at which this band D is attached to the iiange a it is given an outward bend, at e, so as to raise it somewhat above the rim of the cone-frustums to leave a sufficient opening for the smoke, soot, and foul gases coming out of the pipe A. rIhe band D is, moreover, made wider than the space left between the cone frustums, and its edges (which may be inclined or bent upward, as in Fig. 1,) overlap the outer face of the iiange a, so as to fully protect the Vtop opening and the pipe A against rain or snow as well as against return-drafts. The part of the space left between the cone-frustuins that lies below the points of attachment of the band D is divided into two about equal parts by the sheet-metal strips ff, the lower ends of which are fastened to the flange a, either by rivets or solder. These strips are made to project up toward the center of the cone-frustums and inside a slot, g, made in the pipe A, opposite the open space between the same. The slot g is made of aboutthe same width as that of the open space between the cone-frustums, and is extended above and below the point which the strips intersect as they project through said slot inside the pipc A, and to which they are suitably fastened. The lower part ofthe metal cut out of the pipe A yto form the slot or side openings, g, is bent inside the pipe, as shown at 7L, on aline parallel with the strips f, thus forming with the upper part of said strips, projecting inside the pipe A, a continuation of the sluice or air-vent produced in the lower part of the open space below the capband D. The strips f f serve to direct the draft upward to the top of the pipe A and through the slot g, and to prevent its scattering around said pipe. The top of the cone-frustums C is left open, as shown at c, and through this opening and the partitioned space left open between the same drafts will be forced up toward the top of the pipe A, whereby the smoke, steam, vapor, foul gases, and soot will be effectually induced out of the chimney B, whatever may be the direction of the wind.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- A l. In achimney cap and ventilator, the combination of two open cone-frustums attached opposite each other close to the top of the chimney-pipe, and adapted to direct forced drafts upward toward the top of said pipe, lwith a sheet-metal band fastened to the base of said opposing cones and adapt-ed to cover the upper half of the open space left between them, to protect the chimney-pipe against return-drafts and rain or snow, substantially as set forth.

2. In a chimney cap and ventilator, the

cone-frustums C C, having aiiange, a, around their open base, and top openings, c, in combination with the protecting -band D and the chimney-pipe A, substantially'as shown and 5 described, and for the purpose set forth.

3. In a chimney cap and ventilator, the eone-frustums C C, having the dividing-strips f ff, in combination with the pipe A, having the band D and the slots g g and strips 7L h,

ro substantially as shown and described, and for the purpose set forth.

4. In a chimney cap and ventilator, a pipe having side openings and cone-frustums se cured opposite each other, and having open I 5 tops located alternately with and midway bctween the openings in the pipe, to create a blast-draft straight out through the top of the pipe, substantially as set forth.

f 5. A combined ventilator and chimney cap consisting of a pipe having side openings and top opening protected by a weather-band, and

open eone-frustums, as described, whereby a WILLIAM J. KAYSER.
